Description of the invention: [Technical field to which the invention pertains] The present invention has a secret-type electromechanical structure, which is a rotor of a splicable combination of a rotor-shaped rotor piece and a stator piece Fragment, stator segment. The book's financial readings reduce the cost of each rotor segment and stator, and it is difficult to reduce the cost of the mold, the punch machine H, and the fine green waste. You can even use the remaining materials or feet of other processes. It is expected to manufacture products and therefore has great cost benefits. [Prior Art] The brushless motor with the rotor on the outer ring, also known as the externally-rotating motor, is commonly used in applications such as the hub motor of the electric vehicle and the washing machine motor, in which the multi-pole coil is combined with the stator of the inner ring. Each pole coil is wound into a stator, and the stator does not rotate. When the coil is applied with current, it becomes a motor. If the coil is cut by an external magnetic field to generate a voltage, it becomes a generator. The outer circumference of the motor in which the rotor rotates on the outer ring has a large diameter, and the inner side of the rotor is provided with a permanent magnet at each position of each pole of the coil, and each of the permanent magnets is generally formed in a curved shape and is mosaic-incorporated on the inner side of the rotor. There are many ways in which permanent magnets are placed inside the rotor. How to properly position the permanent magnets at the lowest cost and to securely fit them inside the rotor is an important factor in designing such a motor structure. There are many kinds of manufacturing methods for the rotor structure. There are two common types. One is a metal rotor or a cylindrical outer rotor. The inner ring is made by a broaching method. , each groove is used to inlay a piece of permanent 1259638

The magnetic field loop of the coil is better. It is necessary to stamp and manufacture the outer rotor with a larger size. It must make the large-scale, large _ storage and big mocking of the bed, and generate relatively large amount of steel scrap. The point makes it extremely expensive to manufacture, which is not conducive to reducing the total cost of the motor. Due to the above considerations, there are still many shortcomings in the structure of the outer rotor of the electric motor, so bribery is necessary for improvement. The present inventors have recorded this and are actively seeking ways to improve, and the present invention has been produced through the design and experiment of recording. SUMMARY OF THE INVENTION An object of the present invention is to provide a motor structure that is easy to manufacture, reduces waste materials, and can reduce manufacturing costs and material costs. The present invention is mainly used for each layer of the rotor piece group and the stator plate. The segmented combination structure, the multi-stage sheet can be made of sheet metal material's because of the high precision 1259638 understanding and understanding. [Embodiment] [The present invention is shown in the side of the rotor outside the stator of the rotor type motor or electric_, such as the wheel of the washing machine motor car commonly used to illustrate the magnetic field of the present invention: set with fine 15 The stator assembly 1G is provided with a permanent reading subassembly 20, wherein the rotor piece set of the rotor assembly 2 and the stator piece read by the stator are multi-layered to be combined with a body material, and each layer is further divided into a multi-stage combination structure. The manufacture of the article will be described in detail: the stator assembly ίο is provided with a fixed shaft u, the two ends of which are fixed on the bracket 12; and the stator holder 13' is fastened to the fixed shaft 11 by means of the positioning tab 3ι, It can be made of materials with better heat dissipation, such as aluminum, and can be cooled by gas or liquid. It is taken away by the slit of Nozaki 1Q. The stator seat is provided with stator plate 14 and the stator is wound with _ ls and its two end faces The fixing member 16 or a fixing member such as a bolt is inserted through the fixing member 17 of the stator sheet group 14 and the stator end portion 13 to be fixed to the good seat 13. The current and voltage of the coil 15 are derived from the stator outlet hole ιη provided in the middle of the fixed shaft 13_, and the coil 15 is affected by the current to generate magnetic lines of force which are radially pushed out to the permanent magnet 21 via the stator set u 1259638 to form a complete magnetic flux loop. When there is an air gap between the stator sheet group 14 and the permanent magnet 21, the permanent magnet 21 does not interfere with the stator sheet group 14 when the permanent magnet 21 is pushed by the magnetic lines of the coil 15. The rotor assembly 20 includes a permanent magnet 21, a rotor assembly 22 and a casing 23, wherein the permanent magnets 21 are disposed under the rotor assembly 22; the rotor assembly 22 is tightly fitted and disposed within the outer 23, to be combined into At least one bearing 231 is provided on both sides of the outer casing 23 so that the rotor assembly 2 can freely rotate on the fixed shaft n. A brake hub 24 is further disposed on two sides of the rotor assembly 20, and a brake brake (not shown) is disposed in the brake hub 24 for braking the rotor assembly 2b. With the combination of the stator assembly 10 and the rotor assembly 2, the permanent magnet 21 on the inner side wall of the rotor assembly 20 is driven by the magnetic field generated by the coil 15 of the stator assembly 1Q to become a motor; conversely, if the outer rotor casing is driven by an external force, The permanent magnet is cut into the ring ls and the Wei potential becomes the generator. As shown in FIGS. 3 to 6, the rotor piece group Μ is a multi-layer frequency layered combined structure. Each layer system is composed of two or more rotor segments 2a: the splicing portions of the left and right sides of each rotor segment 221 are respectively set. The cartridge 222 and the card slot 223 are combined to form a complete rotor piece group 22 in the circumferential direction by using the card base 2 and the card slot 3. The axial front and rear sides of each rotor segment 221 are respectively provided with positioning bumps 224 (positioning convex or square), 疋, recess h 224a, so that each rotor segment 221 can be axially pressed to have a pre-twist thickness The rotor segment 221, in turn, constitutes a 1259638, sub-sheet set 22 having a predetermined full thickness. Each of the rotor segments 221 is further provided with a magnet slot 225 and a built-in permanent magnet 21 below. The rotor segment 221 can be made of sheet-like sheet metal material. If it is made of Shishi steel material, it can contribute to the improvement of the magnetic flux of the permanent magnet 21. The card shoots 222 card slots 223 provided in the splicing portions of the rotor segments 2 of the rotor piece group 22 can be assembled in various shapes. As shown in Figures 7a to 7d, the joint faces may be 2, 2, or 2, or 22, or 22 or 22, 22 or 22, or DF, DM. Alternatively, the rotor segments can be cut into small segments 221e with each permanent magnet as shown, or cut into large segments 22if with a plurality of permanent magnets. As shown in Fig. 6 and Fig. 8 to 9, the number of coils ls is matched with the number of permanent magnets, and the number of the permanent magnets is as follows: the smoke is reduced or the number is reduced to the number of the poles. The line graph of each pole number is 5S 2丨丨 tower a 7丨』β .
